Hi all, am about to purchase some leca balls to change up my mix for my semi hydro self wicking set up.
I’ve read that leca balls don’t retain nutrients, has anyone tried mixing a bit of zeolite into your self wicking set up to retain nutrients from the reservoir?
The roots suck up the nutrients they need from the reservoir via the wick. All it means that it doesn’t retain nutrients is that unlike soil (which contains nutrients and holds on to them, etc) Leca does not because it’s a rock.
But if you’re already doing semi-hydro in any of the conventional ways, none of them retain nutrients I don’t think, not just Leca.
